Scott, on the issue of fills/breaks, I have not noticed a problem, but it may have been a problem that was fixed by an OS release. As a working pro, I can understand your reluctance to undertake a new learning curve, gig prep, playing technique, board familiarization, etc., etc. At some point, though, you have to decide between a smooth transition to a new board and something that MAY produce better long-term results. There are always trade-offs (pretty wife/lousy cook, great cook/double bagger). Ultimately, you have to do what's good for you.
Peace,
